Yup. What's slowly happening (but really picking up speed here soon) is that the major content companies who own groups of cable and broadcast channels (plus movie and television studios) are going direct-to-consumer with their own streaming services that feature just their own stuff. You may be able to add in other companies' content as add-on subscriptions but you'll be able to buy, a la carte, just the stuff from Disney/ABC or WarnerMedia or NBCU or CBS/Viacom, etc.
Perhaps one day all of this will be retold in a mini-series, like a 21st century version of Pirates of Silicon Valley. The first episode might be called "Stream Wars" about the rise of a brash young hero named Netflix that aimed to transition from last-century DVD to the new-century technology of streaming video, first taking aim at King HBO but then broadening his scope to blow up the entire Cable TV Deathstar.
The second episode will pick up in fall 2020 and be called "Hollywood Strikes Back". But in this story, I'm not betting on the hero of episode one to completely triumph in the end.
The problem is that the RSN’s for example need to be part of a basic package or otherwise their direct to the consumer model does not work due to the rates they would charge.
